Crypto AES-ECB padding byte mechanism.

[Srinivas V]

Hi Team,

If we send 20 bytes of data to AES-ECB 128 bit (CC310/ mbed TLS) Crypto engines for Encryption/Decryption due to bytes padding, how many bytes it will become as final output. Could any body  confirm on this one.

Regards,

Hi Srinivas,

The output is a multiple of 16 bytes, so there will be 12 padding bytes and a total of 32 bytes.
